DISCUSSION

(This Evening Through Monday) Issued at 1229 PM MST Mon Dec 29 2025

Western CONUS ridge will dominate the weather in the period, supporting mild and dry weather most of the week. The region will remain on the NE periphery of the ridge, with northern stream impulses supporting weak cool fronts at times, specifically Wed and and again later Thursday, with seasonally mild Pac air in between. WAA ongoing today as the ridge pushes east, supporting much warmer conds than yesterday, esp the western half. Even warmer tomorrow, with 40s and 50s common, and a few 50s downwind of the BH. Baroclinic zone will fluctuate over the region this week with several weak impulses traversing the north side of the ridge. Most of the area will remain on the warm side of the ridge with seasonally mild conds and breezy winds at times per Pac flow. It is quite possible that one of these impulse comes in a little stronger (namely Wednesday), which could bring much cooler weather to the northeast half than what is currently advertised. Otherwise, dry weather can be expected.
